This invlention rglates to impiapenlients in ipe coupingsan more parti cry to a oupling especially adapted for co'nndcting the adjacent ends of the two metal pipes as- 6 sociated with or connected to the motor water jacket and the radiator of a motor vehicle, al-

though capable of general use.

The general object of the present invention is the provision of an improved pipe 1 coupling capable of being easily and quic connected-to and disconnected from the a jacent ends of two pipes, such asthe pipes above mentioned, and without the necessity of rotating the main body portion of the coupling to effect such connection or disconnection; which coupling includes three metal cou ling parts, an intermediate body member an two separate end members adapted to be connected thereto, each of said end members having a sealing asket secured or anchored thereto so that t e connection of the end members to the intermediate body member properly positions the two sealing gaskets within thecoupling; and which coupling is of extremely simple and inexpensive construction so that it can be made and sold at low cost.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

, In the drawings, Fig. 1 is a side elevation of rtions of the motor water 'acket and the ra iator of a motor vehicle wit the adjacent ends of the two pipes associated with said the coupling and portions 0 said pipes eing enlarged for clearness of illustration; Fig. 2 is a still further enlarged longitudinal sectional view of said coupling with one of its ends connected to one pipe and another pipe in position to have the other end of the coupling connected thereto; Figs. 3 and 4 are cross sectional views on respectively the lines 3-3 and 4-4, Fig. 2; and Fig. 5 is a de- 5 tailed sectional view on the lines 5-5, Figs.

3 and 4.

Referring to the drawings, 1 represents a portion of the radiator and 2 a portion of the motor water jacket of a motor vehicle, and the present coupling was especially designed "hate in s for connecting the adjacent ends of the pipes 3 and 4 'vely associated therewith or s a di 1 a 11 1mg ai coup gincu eat reecou arts a body or intermediate member, which i the li. main part of the cou lin and two separate end members adap to connected to and disconnected from said body member. Said body member is of sheet metal having a cylindrical. middle portion 6, two inwardly l0 ta red intermediate portions 7 and two annu ar, outwardly and forwardly curved gasket-enga in}; end portions .8 which termiort outwardly extending annular e two end members 10 and 11, which are identical throughout and therefore interchangeable, are also formed of sheet metal and each has a central pipe receivin opening 12, a curved gasket engaging an carryin portion 13 o annular form, a short annu ar flange 14 extendin outwardly from the outer end ofsaid curve portion, and a plurality of locking tongues 15 circumferentially. spaced about the outer ed e of said flange 14, said tongues being initiafiy generally perpendicular to said flange and extending there from in the direction in which the asket carrying portion 13 is urved, as clear y indicated at the right he d end of Fig. 2. The tongues 15 of the two end members 10. and 11 are-adapted for locking engagement with the annular flanges 9 of the coupling body member, as will more fully appear.

The inner surfaces 17 of the gasket carrying portions 13 of the two end members are each provided with a circumferentially spaced series of projections or prongs 18, six in the present case. These projections or prongs are adapted to be pushed into and thereby anchor or secure to the inner surface of each end portion 13 a sealing sket 20, which is of annular form, circu ar in cross-section and of rubber or other yielding material. One simple way of forming these projections or prongs is to shear or unch them from the end portions 13 and t is is the way illustrated in the drawings.

The adjacent ends of two pipes, such as l the pipes 22, 24 in Fig. 2, are connected by 00 members from the cou ling which can be easily an ends and provided at 2 1,a4e,1oe my improved coupling by pushing the two of generally circular shape in cross section end members 10 and 11, with their askets arranged in each of the two gasket-receiving secured thereto, over the ends of sai pipes, as indicated with the right hand end member 10 in Fig. 2. The coupling bod member is then brought to the position in icated 1n Figgil with its end portions 8 telesco ing the en of the pipes. The end mem rs, in turn, are then moved agzinst the ends of the coupling bod mem r, until the outwardly extending anges 14 of said end members engage or abut the outwardl extendinggnd flanges 9 of said bod mem r. The loc 'ng tongues 15 of the en member flanges 14 are then bent inwardly back of the body member flanges 9, as clearly indicated in Fig. 5, which securely locks the coupling end members to the coupling body member. To remove the cou ling from the pipes, it is only necessary to isconnect the coupling end bod member, quickly one by inor the like beneath the serting a screw driver the end members and locking tongues 15 of ryin said tongues outwardl to free them roin ockin en a ement wit the flan 9 of the cou 1mg y member, all as w' 1 be readily un erstood.

The curved end portions 8 of the coupling body member cooperate with the curve portions 13 of the couplin end members to rovide annular grooves or the sealing gas ets 20, and these grooves may be made of considerable depth in the present improved construction.

Since it is not necessary to rotate the coupling body member in connecting or disconnectlng two pipes, the ends of said pipes may be out of alignment and the coupling body member of angular shape. Sometimes, angular coupling body members might be desired in places where there is insuflicient space to rotate them, and in such laces, the present coupling would be especia y useful.

What I claim is:

A couplin for a pair of adjacent, substantially aligned pipe ends, comprising a tubular sheet metal body member adapted to substantially span the space between said pig:

each of its two en with an outwardly curved, annular, gasketengaging1 portion terminating in an outwardly exten ing, annular flange, two sheet metal end members each having a central pipe-receiving opening and an outwardly curved, annular, gasket-engaging portion terminating in an outwardly extending, annular flange, the gasket-engaging portions of said body member and of said end members together forming at each end of said body member, when the flanges of said end members are in abuttin relation with the flanges of said body mem er, an annular, gasket-receiving groove of generally semi-circular shape in cross section, an annular sealing gasket ves thus formed, and locking tongues adapted, when the flanges of said end members are in abuttin relation with the flanges of said body mem r, to be bent over and back of one of the flanges of each abuttin pair of flanges, said ton es being carri y the other flange of eac abutting pair of flanges, whereby said end members are locked to said body member with the flanges of said body and end members in abuttin relation.

In testimony whereof I hereby a x my signature.
